ATLANTA, Georgia (AP) – A person in protective clothing climbed out of an ambulance at an Atlanta hospital where a U.S. doctor infected with Ebola was being brought for treatment.

Dobbins Air Reserve Base spokesman Lt. Col. James Wilson says the patient arrived Saturday at the base. A Grady hospital ambulance with red markings was flanked by a few SUVs and police car en route to Emory University Hospital about 15 miles from the base.

Samaritan’s Purse missionary group tells The Associated Press that Dr. Kent Brantly is the patient.

He worked at a hospital in Liberia that treats Ebola patients.

He and another aid worker will be treated at a special isolation unit at Emory University Hospital.

A private jet is being used that is outfitted with a special, portable tent designed to transport patients with highly infectious diseases.
